The well-balanced diet and the "at risk" micronutriments: a forecasting nutritional index.

The forecasting nutritional index is the list of micronutrients whose intakes do not amount to 80% of the recommended allowances, this list being determined on the basis of a balanced diet. This kind of diet allows to bring out the micronutriments which are the least likely to be found in the diet. The food and epidemiological studies results allow to confirm the forecasting nature of this index.
